The Betrayal is a low-budget 1957 British film directed by Ernest Morris and starring Philip Friend and Diana Decker.

[2] Michael McCall is a former World War II pilot who was blinded while imprisoned by the Nazis.

As he is now unable to identify the traitor by sight, McCall is aided in his search by model Janet Hillyer.

The result is that there is some rather violent and evident wrenching of the plot to involve the blind man in tight corners and then to extricate him again.

The only really interesting point – whether McCall will forgo his revenge when he catches up with Bartel – is muffed by the entry of the police.
